Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and carbohydrate for metabolism; sodium and chloride are major electrolytes that maintain osmotic pressure and acid-base balance; potassium is essential for nerve impulse transmission, muscle contraction, and cardiac function.
Magnesium sulfate causes decreased release of acetylcholine at the neuromuscular junction, reducing muscle contractility. It also blocks calcium channels, leading to vasodilation and anticonvulsant effects.
Intravenous infusion. Dose depends on patient's fluid, electrolyte, and caloric needs. Typical adult: 1000-2000 mL/day at 1-4 mL/min. Rate should not exceed 10 mL/min. Potassium content is 20 mEq/L; maximum potassium infusion rate is 10-20 mEq/h, not to exceed 240 mEq/day.
IV: 1-4 g as a 10-20% solution, rate not exceeding 1 g/min; for eclampsia: 4-5 g IV bolus then 1-2 g/hour IV infusion.

Glucose: 1.5-2.5 hours for exogenous glucose clearance. Potassium: terminal half-life 7-12 hours in normal renal function. Sodium: no defined half-life; body content regulated by renal excretion.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Renal: D-glucose is completely reabsorbed under normal conditions; excess is excreted unchanged. Potassium is primarily excreted by the kidneys (90%), with minor fecal (10%) loss. Sodium is predominantly excreted renally (95%), with small amounts via sweat and feces (5%). Chloride follows sodium excretion.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
